An information processing apparatus includes: a determiner that determines an area including a handwritten figure from image data; a recognizer that recognizes a handwritten character from the handwritten figure; an acquirer that acquires a file name; and a file generator that generates a file with a file name based on a handwritten character when the recognizer recognizes the handwritten character based on the image data and generates a file with the file name acquired by the acquirer when the recognizer does not recognize a handwritten character.

Methods and systems for improving the robustness of wireless communications. The methods and systems provided transmit data packets over a first isochronous stream and transmit one or more supplemental data packets over the same time intervals. The one or more supplemental data packets are used to re-create and/or enhance at least a portion of one or more data packets of the plurality of data packets that have already been sent. Alternatively, the one or more supplemental data packets are used to create and/or enhance at least a portion of one or more data packets of the plurality of data packets that will be received during the next isochronous intervals. The methods and system described herein allow for increased robustness by allowing for better retransmission with correctly received packets and the methods set forth herein work with any Bluetooth broadcaster sink without modification.

Various schemes pertaining to optimization of binary convolutionally encoded (BCC) interleaver and low-density parity-check (LDPC) tone mapper for distributed-tone resource units (RUs) and multi-resource units (MRUs) in 6 GHZ low-power indoor (LPI) systems are described. An apparatus processes a plurality of subcarriers of a RU to generate a distributed-tone RU (dRU) or a distributed-tone multi-RU (dMRU). The apparatus then transmits the dRU or the dMRU to another apparatus. In processing the plurality of subcarriers, the apparatus codes a plurality of information bits by either LDPC encoding or BCC encoding and transmitting the plurality of subcarriers with one or more optimization parameters using a LDPC tone mapper or a BCC interleaver.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may communicate an indication of an updated error vector magnitude (EVM) requirement. The transmitting device may transmit a communication using transmit processing associated with the updated EVM requirement. Numerous other aspects are described.

A network system includes access points and wireless devices. Each wireless device can exchange data with at least one access point that includes a diversity matrix defining at least two data exchange connections between a first wireless device and at least one access point for exchanging data between the first wireless device and the at least one access point. The diversity matrix indicates a space domain with at least one access point, a frequency domain with at least one data transmission frequency value, and a time domain with at least one data transmission time. Each data exchange connection is defined by an access point, a data transmission frequency, and a data transmission time, selected from the diversity matrix. The at least two data exchange connections between the first wireless device and the at least one access point are configured to transmit the same information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may transmit, over an unlicensed carrier, an initial transmission of a transport block (TB) satisfying a condition and an indication that a retransmission of the TB will be communicated over a licensed carrier. The apparatus may retransmit the TB over the licensed carrier based at least in part on a failure of the transmission of the TB over the unlicensed carrier. Numerous other aspects are described.

Techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (PRS), also referred to as PRS beamforming. In an example method, a plurality of directional PRSs are generated for at least one cell for a base station, such that each of the plurality of directional PRSs comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. The plurality of directional PRSs is transmitted within the at least one cell, such that each of the plurality of directional PRSs is transmitted in the direction of transmission. A mobile device may acquire and measure at least one of the directional PRSs which may be identified using the associated signal characteristic. The measurement may be used to assist position methods such as OTDOA and ECID and to mitigate multipath.

In one example, a transmitter wireless communication device may be configured to encode k data packets into n encoded packets according to a Network Coding (NC) scheme, wherein k is equal to or greater than two, and wherein n is greater than k. For example, the transmitter wireless communication device may be configured to transmit the n encoded packets over a plurality of wireless communication resources, for example, by transmitting at least one first encoded packet over a first wireless communication resource and transmitting at least one second encoded packet over a second wireless communication resource. For example, a receiver wireless communication device may be configured to determine the k data packets, for example, by decoding at least k received encoded packets out of the n encoded packets according to the NC scheme.
